MIDWEST A

The Midwest A deposit, formerly known as the Mae Zone, is roughly three kilometers northeast of the Midwest deposit. Denison has a 25.17% interest in the project with AREVA Resources Canada Inc. (ARC) owning 69.16% and OURD owning 5.67%. ARC is the operator.

During the 3,000 metre, 2007 fall drill program, hole MW-753 successfully confirmed sandstone-hosted mineralization on the west extension of the discovery and a second drill hole (MW-755) intersected 21.9 metres of 3.20% eU3O8, potentially indicating a new high-grade zone to the southwest.

In February 2008, Denison received a 43-101 resource estimate for Midwest A showing an indicated mineral resource of approximately 5.8 million pounds of U₃O₈ at an average grade of 0.57% U₃O₈ and inferred mineral resources of 4.3 million pounds at an average grade of 21.2% U₃O₈ ⁽¹⁾.

Because of its proximity to the Midwest deposit, Midwest A will benefit directly from the infrastructure (roads, power, water treatment and mill expansion) that will be built to support the development of the Midwest deposit.

⁽¹⁾ The Company has filed the "Technical Report on the Midwest A Uranium Deposit of Saskatchewan, Canada," dated January 31, 2008 on the Company’s profile on the SEDAR website at www.sedar.com. A cutoff of 0.05% eU was used.
